Mobs dying to traps/environment in vaults

[Hachem_Muche]

I've noticed a lot of mobs are killing themselves on traps in vaults in this version of the game. Apparently, they'll detect me before I get to them and start running back and forth over traps (I'll see a bunch of damage messages show up in the vault area.) until they die -- leaving treasure and items spread about. I've noticed this also happens in the armory leaving one very tough room devoid of mobs by the time I get to it.
